BACKGROUND 1. Technical Field

The present disclosure generally relates to shoulder straps, and, more particularly, to shoulder straps applicable to a baby carrier, which can be more effectively adjustable to fit different users' needs so the user does not have to purchase different carriers for the different shoulder straps thereof.

2. Description of the Related Art

Generally, baby carriers of prior art have various forms. The structure of shoulder straps is one of the crucial features of the baby carrier, which directly affects the comfort of carrier for the user. In order to reduce the pressure put on the user's shoulders from the baby's weight, a baby carrier with its straps comprising the configuration of decompression blocks is usually used as a solution. However, the decompression blocks are known to be thick and non-breathing. Therefore, users would be sweltered by these straps in hot weather. On the other hand, thinner and more breathing shoulder straps cannot effectively distribute the pressure from baby's weight.

FIG. 9 illustrates a baby carrier disclosed by U.S. Pat. No. 8,590,757 B2. The baby carrier comprises a belt 70, a carrier body 80, a first shoulder strap 90 and a second shoulder strap 95. The first shoulder strap 90 and the second shoulder strap 95 are formed on the two sides of the carrier, respectively, and each of them has a decompression block 91. The decompression block 91 reduces pressure. However, the decompression block 91 is so thick that it would make the user sweltered and uncomfortable in hot weather.
